Preheat oven to 450 degrees F.
Cook sausage in the olive oil in a large skillet over medium-high heat until browned and crisp. Remove from heat.
Press the thawed dough into a 15-inch circle. Top dough with spinach and sun-dried tomatoes. Top with chopped scallops, baby clams and half of the sausage, then both cheeses. Sprinkle with dried oregano. Bake 10 to 12 minutes, until cheese melts.
Serve with a simple bagged and pre-washed green salad and a bottled vinaigrette.
